containing crystalline alumino-silicates, e.g. molecular sieves

Full Title

Refining of hydrocarbon oils using hydrogen or hydrogen-generating compounds > to change the structural skeleton of some of the hydrocarbon content without cracking the other hydrocarbons present, e.g. lowering pour point; Selective hydrocracking of normal paraffins > characterised by the catalyst used > containing crystalline alumino-silicates, e.g. molecular sieves
